This is a ATA-7 compliant device interface core used for interfacing custom devices to IDE controller. Core is targeted for SOC implementations in ASIC and FPGA.
Features:
- PIO modes 0-4
- IORDY signaling for PIO cycle extension
- Multi-word DMA modes 0-2
- Ultra DMA modes 0-6
- Programmable timings for PIO and DMA modes
- Support for Ultra DMA pause and termination
- Standard slave Wishbone interface to microprocessor/microcontroller
- Interrupt generator for IRQ driven software driver implementation
- Automatic handling of BSY and DRQ bits
- DMA engine and master Wishbone interface for data transfer
- Small register FIFOs for transmit and receive data
- Acts as a single, master ATA/ATAPI device on ATA cable
- 66MHz clock for UDMA133 (mode 6) operation
